The address on the writ or other bailiff document is wrong.

Where an Act authorises a document to be served by post, the service is deemed to be effected, unless evidence to the contrary is proved.^[1]

The writ having a wrong enforcement address is evidence the bailiff did not give a Notice of Enforcement.^[2]

If the original debt is in dispute, the debtor may apply to stay the enforcement and set aside the judgment.^[3]

If the original judgment is not disputed, the enforcement fees are not recoverable, because the address on the writ is evidence the bailiff did not use the Schedule 12 procedure by giving a Notice of enforcement,^[2][4][5] and the debtor may apply to the court for a detailed assessment.^[6][7]
